6-Week Body Makeover promises 30 pounds in 6 weeks if you follow it religiously it works. You can keep doing it for another 6 weeks if needed. BUT, as soon as you go off of it the weight will come back really fast. I know you probably want to lose weight for a special reason or event, not get told how awful you are for wanting to do it. If you must, this is one of the better ways to lose a lot of fat really fast. It is just not sustainable. Lots of luck to you.
